The Hitec battery connector has three wires, one for the battery, one for the Axon,
and one for a battery charger. This lets you embed the battery in your robot
without having to open it up to charge your robot or turn it on.

Remember, if your receiving junk data, that means you improperly
set up the baud rate but everything else is working fine. It also
means you should read the FAQ on UART gibberish.

If you don't like HyperTerminal,
another popular terminal program to try is
Tera Term.

note: The first 15 Axons shipped in 2009 had an incorrect baud rate pre-installed on the factory installed test program.
Nothing major, but if you want to test the USB before programming the Axon (not required),
simply bootload up the newest test program to overwrite the old one.

STEP 4: Connect Sensors & Servos

Servos can be connected to any header on the left and right of the Axon. Ground (black wire)
is always the outside row, and red (power) is always the center row.

Analog sensors, such
as the Sharp IR Rangefinder should always be connected
to the regulated 5V bus. The 5V bus is the first 16 (ADC #0-15) headers on the top header row of the Axon.

An example:

You can also take power from the Axon for other external devices as shown with
the red and black connector on the left:

A UART connection is demonstrated on the right.

STEP 5: Connect UART

The UART is a way for the Axon to communicate
with other hardware through serial, such as a camera,
bluetooth, or GPS. It's as easy as plug and play.

T is for transmit, R is for receive, and G is for ground (make sure external devices share a common ground!).

STEP 6: Mount Axon to Robot

It is recommended to mount your Axon to your robot using spacers at least .25" long.
Here is an example with 1" spacers and four screws (not included):
